Thavasi

Thavasi is introduced as an influential do-gooder landlord who commands respect in the village. He and his wife arrange the marriage of their son Boopathi to Priyadarshini, laying out the social order of the community. The setup shows how status and duty influence personal choices in this rural setting.

Sankarapandi's brutal history is revealed: he raped and killed Thavasi's sister after marrying her. Despite this, he seeks to knot his daughter with Boopathi, continuing his grip on the family through marriage. The tension here underscores themes of vengeance and lineage.

Thavasi openly insults Sankarapandi to protect his prestige and boldness. In response, Sankarapandi moves to have his daughter married to Thangarasu, Maragathammal's son, instead of Boopathi. The confrontation reshapes the alliances in the village.

Boopathi's engagement with Priyadarshini is formalized, and the two young people grow fond of each other through chance encounters. The romance runs against rigid familial calculations, foreshadowing future conflict. The engagement sets the foundation for a love-driven arc within a web of duty.

Shortly after, Thangarasu is accused of stealing temple jewels, and Thavasi quickly judges him guilty. The accusation reveals the fragility of appearances and the sway of a powerful patriarch's verdict. This decision sows seeds of tragedy that will unfold.

The next day, Thangarasu dies by suicide, unable to bear the stigma of the accusation. The film implies his innocence, hinting at a miscarriage of justice. His death becomes a catalyst for questioning Thavasi's judgment.

A mute person is arrested as the thief, challenging the certainty of the earlier verdict. Maragathammal's doubts about Thavasi's infallible judgment begin to spread. The community begins to sense that truth may lie beyond rigid pride.

To atone for the wrong done to Maragathammal's son, Thavasi decides to give Boopathi to Maragathammal as a form of restitution. The gesture upends Boopathi's status and tests loyalties within the household. It marks a turning point in how power and justice are managed.

Maragathammal despises Boopathi after receiving him as a son, and treats him badly. Boopathi endures mistreatment while keeping faith in truth and duty. The mistreatment fuels his resilience and moral stance.

Sankarapandi intends for his daughter to marry Boopathi, now a son of Maragathammal, as part of the arranged match. The convoluted alliances keep shifting as commitments tie and re-tie around lineage. The dynamic shifts the stakes for everyone involved.

Before his own marriage, Boopathi rescues Thanagarasu's mentally slow sister from a sexual assault by Kottai Perumal and helps reform Karmegam, Thangarasu's brother-in-law who mistreated his wife for dowry. These acts reveal Boopathi's hidden courage and his influence in changing people around him. The acts also start to realign the village's moral compass.

In a chance encounter before his marriage, Boopathi meets Sankarapandi's daughter again and discovers the mute thief's secret. He captures the thief and forces a confession that Sankarapandi staged the theft and Thangarasu's murder, making it appear as suicide. The truth begins to crack the façade of the earlier judgments.

The confession exposes Sankarapandi as the mastermind behind the jewel theft and Thangarasu's murder, overturning Thavasi's earlier verdict. It suggests that the real crime was hidden in plain sight and that justice depends on uncovering the truth. The village must confront the consequences of its past decisions.

Boopathi finally marries Priyadarshini, and their union culminates in Priyadarshini's pregnancy with twins. The story closes on a note of renewal despite the earlier injustices. The twins symbolize a new chapter and a chance at a more just order in the village.
